Bacillus spp. strains’ growth and biofilm formation under different saline conditions. (A) The visual representation of strains’ growth on solid LB media (a–h) with different NaCl concentrations (1–18%). Each number indicates strain: 1. FZB42, 2. B168, 3. EZ-1509, 4. CJCL2, 5. LLCG23, 6. NMCN1, 7. SYST2, 8. LNXM65, 9. TS1, 10. LSSC3, 11. GBSW11, 12. LNXM37, 13. LLTC93, 14. GBAC46, 15. NMCC4, 16. LNXM10, 17. LLTC96, 18. GBWC18. (B) Shows the graphical presentation of optical density at different time intervals calculated at (OD600) of high halotolerant strains (MNCN1 and LLCG23) as compared to FZB42 grown in Liquid LB media with different salt concentrations. (C) The biofilm formation potential of selected strains grown under different NaCl concentrations (1–18%) for 5 days at 37 °C. The experiment was repeated thrice with similar results.
